The basic principle attaching anti-AA flares to a helicopter is simple:add "Incomingmissile" EH, when it's triggered - wait for rocket to come close, fire flares - but what is next ?i.e. what is the best way to make missile hit the flare ? I searched through my ofp addons folder (there's a banch of addons with this feature) - the best examples i saw just force missile to turn with some angle thus avoiding hitting the heli.Is there better ideas ? I'm still looking for simple and effective way. What about making flare with big FireGeoLOD - missile can hit it occasionally ? Is it possible to change missile target via script when it's already fired ?

i don't like big complicated script systems - it's hard to find what you need and export to your addon. But thanks to the comments you gave to all the scripts - it didn't take me too long mando_missileecm.sqf adds "Incomingmissile" EH. Thus mando_missiles\units\mando_incoming.sqf is launched. mando_chaffflares.sqs is executed too, but i see it's for your missile system only + there're even no drop effects It is "able to attract mando_missile missiles" (c), but i'minterested in standart weaponsMissile evading part:

kinda strange... in simple words this code just make missile fly straight with constant speed. The simpliest idea i have ever saw. though i don't know what for you set _constant_ speed Of course, missile will be evaded, but you know - that's not the idea i'm looking for

This is obsolete and not used anymore, mando missiles replaces all ArmA missiles at launch time and normal mando missile flares or chaff attrack them. If you dont replace the ArmA missile by your own, ArmA will try to guide it to the target while you fight in the other way trying to move it away, resulting in a weird trajectory.

EDIT: Flares or chaff are drawn for both, mando and ArmA ones in any case and in every client/server machine.
